  The conventional monitoring system has a monitoring camera and sensor installed in each part of the monitoring area, a communication facility that transmits such monitoring information to the monitoring room, and a monitoring display and alarm device installed on the monitoring room side. It becomes a system configuration, and many facilities / devices are installed to strengthen the monitoring function. For this reason, the monitoring system is a large-scale design and installation work that requires a long period of time for its construction, and a strict monitoring becomes a very expensive system with a large number of monitoring devices and devices.

Under these circumstances, the conventional monitoring system can be applied only to a semi-permanent monitoring system, and requires a quick monitoring system and strict monitoring, but the monitoring period is relatively short. This makes it difficult to apply to monitoring of a monitoring target that only requires general monitoring.
This kind of monitoring system is required, for example, when a ship that requires strict monitoring is repaired with a dog or anchored at a port, the monitoring period is as short as several months or weeks. become. When an aircraft that requires strict monitoring is temporarily stored in a temporary base, the monitoring period is as short as several weeks at most. Further, when various event venues are temporarily set up, the monitoring period is a short period of only the event period.

  As described above, a rapid monitoring system needs to be established and strict monitoring is required, but the conventional monitoring system cannot be applied to monitoring of a monitoring target having a relatively short monitoring period. Therefore, for this type of monitoring, it is conceivable to enclose the area around the monitoring area with a fence and arrange security guards around the area for 24 hours, but a large number of security personnel are required to strengthen the monitoring function. . In addition, monitoring of the entrance / exit gate requires authentication of a person / vehicle permitted to enter / exit the monitoring area and a person / vehicle not to enter / exit. It takes a lot of time and effort, and simple authentication such as an introduction permit can lead to illegal intrusion.

  The purpose of the present invention is to install and remove monitoring equipment in a short period of time, greatly reduce the cost of maintenance equipment and maintenance, and quickly and reliably monitor and authenticate people / vehicles at the entrance gate and in the monitoring area. It is to provide a monitoring system.

  In order to solve the above-mentioned problems, the present invention combines an RFID device having an RFID tag and an RFID reader as a monitoring sensor, a human sensor that senses a person, and an image analysis device that detects intrusion and suspicious behavior. The movement / presence identification of the person / vehicle is performed by reading the RFID data when the human sensor detects the person / thing, and comparing the RFID data with the previously registered RFID data. Allows determination and authentication of permission / non-permission of entering / exiting the location.

  In addition, as a monitoring camera, a PTZ camera that can be remotely panned, tilted, and zoomed is used in combination with a fixed camera, so that it is possible to acquire a monitoring image corresponding to the widening / complexity of the monitoring area with a small number of cameras.

  In addition, as a monitoring information processing apparatus for intrusion monitoring / image monitoring into a monitoring area, a monitoring computer and a monitoring camera are provided with a personal computer with an image monitoring function and an image analysis apparatus connected via a wired or wireless LAN, and registered in advance. When a set suspicious behavior is detected by image analysis, a personal computer with an image monitoring function can be used to monitor the behavior of a person / vehicle, to identify the movement / presence of a person / vehicle and to enter / exit, and to create a database of photographed images And image analysis for extracting the motion of the person / vehicle in the photographed image by the image analysis apparatus.
